背景

这两天看到Manjaro升级还是挺频繁的,今天上午还看到更新Grub.当然这不是重点,事情是这样的今晚开机是留意下电脑发现没有开机引导界面,因为工作和家人需要默认还有Win10系统(双系统),可是这次进入Manjaro登陆界面.tg社群寻求帮助才明白原来还是跟最近的升级有关系.

预知后事如何,请继续耐心看下去....

案例

哈,真当我讲故事呢?
直接来处理方法吧,相信大家的时间都是很宝贵滴!

以下内容来源于:Manjaro社区论坛,因本人英语一般般,直接托原文以免误导.

After the most recent update on 8th March 2021, the Grub menu disappeared.
I managed to get the menu to reappear by running the following command

sudo nano /etc/default/grub

and then editing the grub file and changing the following

GRUB_TIMEOUT_STYLE="hidden"

to

GRUB_TIMEOUT_STYLE="menu"

sudo update-grub
sudo grub-mkconfig -o /boot/grub/grub.cfg

However both my Windows 10 (on the same SSD ) and my 2nd (backup) Manjaro installation on a second drive HHD do not appear in the Grub menu anymore. They are both on GPT partitioned drives with EFI boot.

After running os-prober I get the following

sudo os-prober
/dev/sda2@/EFI/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi
/dev/sdb5:Manjaro Linux (20.2.1):ManjaroLinux:linux

I can boot into both Windows 10 (SSD) and my 2nd Manjaro installation (HDD) if I choose the appropriate device from the BIOS, but they no longer appear in my Grub menu.

If anyone can help that would be greatly appreciated. This exact problem has also occurred on one of my separate machines which is much older, Windows 10 was lost from the Grub boot menu.

依然没有Win10引导?

走了一遍上面流程,是不是发现还是没出现Win10引导菜单?
这一步挺重要.

Manualy add the line GRUB_DISABLE_OS_PROBER=false to /etc/default/grub
Run sudo update-grub

记得添加命令后再重新生成菜单配置文件,而后重启看下是不是又回来了?

尽情享用!!
